PUBLIC SCHOOL SEGREGATION AND JUVENILE VIOLENT CRIME ARRESTS IN METROPOLITAN AREAS

Previous research has established an association between residential segregation and violent crime in urban America. Our study examines whether school‐based segregation is predictive of arrests of juveniles for violent crimes in U.S. metro areas. Using Census, Uniform Crime Report, and Common Core data for 204 metro areas, a measure of school‐based racial segregation, Theil's entropy index, is decomposed into two components: between‐ and within‐district segregation. Findings reveal evidence of a significant interaction term: Within‐district segregation is inversely associated with arrests for juvenile violence, but only in metropolitan areas with higher than average levels of between‐district segregation.     

The market for (Ir)reproducible econometrics

Context: As the volume and complexity of research have increased, the amount of time spent on Institutional Review Board (IRB) review has decreased. The complexity of research has expanded, requiring increasingly specialized knowledge to review it. Dilemma: Under the current system, increasing numbers of research studies requiring expertise in ethics, new technologies or diverse study designs place a substantial burden upon local IRBs and often result in substantial variability among their reviews. This lack of uniformity in the review process creates uneven human subjects’ protection thus undermining the intent of the Common Rule. Objectives: To outline a scenario for expert centralized IRB review via implementation of a national virtual IRB review system overseen by the Office for Human Research Protections (OHRP). Conclusions: The complicated ethical issues and science involved in much of current research warrant an expert review panel. Centralized review would enable expert review specific to the research at hand, ensure consistency in human subjects protection, reduce the burden on local IRBs, and may reduce time spent obtaining approval. A centralized virtual system would allow IRB members to remain at their institutions while providing unprecedented expert review through currently available technology, and make information regarding monitoring and adverse event reporting available online in real-time.     

Enforcement is the Name of the Game: An Essay on the Immigration Inspector at Work

Abstract

This article concerns the work of immigration inspectors who inspect parties entering the country to determine if they merit entry according to law. Focusing on aspects of their working environment, this paper discusses ways inspectors have sought to organize daily activities. Faced with an uncertain decision-making process, lacking adequate preparation to deal with an unpredictable public, and working within a decentralized administrative structure, inspectors are nonetheless confronted by strong bureaucratic pressures for uniformity and consistency in their actions. Attempting to reconcile these conflicting demands, personnel have utilized various strategies for reducing overall risks associated with their work. This analysis casts doubt on the applicability of such theoretical constructs as “formal” or “informal” organizational processes when examined through an action perspective.     

Social Origins and Transformations: The Changing Role of English Housing Associations

Following the suggestion of Ragin (1998, Voluntas, 9(3), 261–270), this article uses social origins theory (Salamon and Anheier, 1998, Voluntas, 9(3), 213–248) as an heuristic device to explore change in a specific field of nonprofit activity; the English housing association sector. Conventional histories of the sector in the twentieth century suggest a succession of eras with different policy drivers. These eras can be seen as consistent with shifts in welfare regime from liberal to social democratic (after 1919) and to neo-liberal/neo-corporatist (after 1980). Examples drawn from a panel study support the analysis of Esping-Anderson (1990, The Three Worlds of Welfare Capitalism, Princeton University Press, Princeton) that underlying the apparent stability of welfare regimes there are constant processes of negotiation and conflict which may lead to transformations at organization, sector, or regime level. Rather than simply responding to policy drivers, some housing associations have been able to influence the environment in which policy is made and thereby to shape their own and the sector's transformations.     

On the incidence–prevalence relation and length‐biased sampling

For many diseases, logistic constraints render large incidence studies difficult to carry out. This becomes a drawback, particularly when a new study is needed each time the incidence rate is investigated in a new population. By carrying out a prevalent cohort study with follow‐up it is possible to estimate the incidence rate if it is constant. The authors derive the maximum likelihood estimator (MLE) of the overall incidence rate, λ, as well as age‐specific incidence rates, by exploiting the epidemiologic relationship, (prevalence odds) = (incidence rate) × (mean duration) (P/[1 ? P] = λ × µ). The authors establish the asymptotic distributions of the MLEs and provide approximate confidence intervals for the parameters. Moreover, the MLE of λ is asymptotically most efficient and is the natural estimator obtained by substituting the marginal maximum likelihood estimators for P and µ into P/[1 ? P] = λ × µ. Following‐up the subjects allows the authors to develop these widely applicable procedures. The authors apply their methods to data collected as part of the Canadian Study of Health and Ageing to estimate the incidence rate of dementia amongst elderly Canadians.

Cycling of simple rules in the spatial model

McKelvey [4] proved that for strong simple preference aggregation rules applied to multidimensional sets of alternatives, the typical situation is that either the core is nonempty or the top-cycle set includes all available alternatives. But the requirement that the rule be strong excludes, inter alia, all supermajority rules. In this note, we show that McKelvey's theorem further implies that the typical situation for any simple rule is that either the core is nonempty or the weak top-cycle set (equivalently, the core of the transitive closure of the rule) includes all available alternatives. Moreover, it is often the case that both of these statements obtain. Received: 13 October 1997/Accepted: 24 August 1998     

Collective Self-Esteem and Coping Strategies among Vietnamese American Adolescents

This article reports on the “social empathy attitudes” results that were part of a larger study on empathy in college students at a large research university in the Southwest. Two hundred ninety-four students completed the Social Empathy Assessment Index (SEAI). The research hypothesis was that students of color would have higher levels of social empathy attitudes than Caucasian students. The statistically significant SEAI items suggested that Latino students identify as more collectivist and more optimistic and have higher levels of social empathy attitudes. Latinos may be more willing to help a stranger than either Caucasians or members of other racial groups.
